In Fig. 5, 1',-2', 3', 4', are openings in the regulating plate c, c', corresponding to openings, 1, 2, 3,4, in the valve-casing, part B'; b', also corresponds to the opening b, in the valve-casing, part B'; V", is the pin, firmly fixed, in the plate c, o'.

In Fig. 6, F, is the screw-arm; V', is a movable flexible arm one end of which is movably secured, within the screw-arm F, the other end of arm V', movably' engages the pin V", which fixed to the regulating plate c, c'.

In Fig. 7, the regulating plate c, c'. and the screw-arm F, are 'in place, showing, the openings, 1, 2, 3, 4 intersected by the .openings The special features of my device are described as follows,-The valve-casing B, B', B", is provided with inlet and outlet openings, to allow a flushing stream to pass through said valve-casing. The valve-casing, part B", incloses a main valve P, and

a relief valve O. The said main valve P, is a gravity actuated valve, with a smooth, plain,

perpendicular surface, fitting into the said valve-casing, partV B, in 'such a manner, as to form a confined chamber X, within said valve-casing, part B", above the said main valve P. The said main valve P, has a gasket e, e', secured toits uppersurface, by meansof the plate d, d', forming a liable seat, for the relief valve 0. The sai main Vvalve P, has a concave bottom, forming a thin cutting edge, which contacts the valveseat a, a', formi said main valve has a depending valvestem P'. The said main valve P, and its depending valve-stem P', are provided with a continuous axial passage-way, extending admitting of rotation,

a positive closure. The

AO', projects through-tbe distal end, of the depending valve-stem P', entirely filling the opening, at its exit b' thereby givin proper :xlinementvand support, to the dista en d. 0f the said valve-stem O'.

The flushing stream is controlled, by the circular regulating plate c, c', actuated by the screw-arm F. The said 'plate c, c', is provided with openings, 1', 2', 3', 4', see Fig. 5, corresponding to openings, 1, 2, 3, 4, in the valve-casing, part'B'. see Fig. 7. The said screw-arm F, is provided with a flexible, movable arm V', oneend of which movably engages the pin V", bn the plate c, c', while the other end, of the arm V', is movably secured, admitting of rotation, within the screw-arm F, see Fig. 6. By turning the screw-arm F, to the right, a corresponding pressure is given to the arm `V', which pushes upon the pin V, on the regulating plate c, c', causing the said regulating plate 0, c', to rotate upon its axis, from, its starting position, and presenting the openings, 1', 2', 3', 4', in the plate o, c', to the openings, 1, 2, 3, 4, in the valve-casing, part B'. When the openings, 1', 2', 3', 4', in the plate c, c', fully correspond, to the openings, 1, 2, 3, 4, in the valve-casing, part B', see Fig. 2, we have the maximum flushing stream. By turning the screw-arm F, to the left, we reverse the action, and rotate the plate c, c', upon its axis, toward, its starting position, thereby causing the openings, 1', 2', 3', 4'

in the regulating plate c, c', to intersect, the v openings, 1, 2, 3, 4, in the valve-casing, part B', and correspondingly decrease the size of the said openlngs, see Fig. 7. By turning the screw-arm F, to the right or to the left, thereby changin the size of the-said openings, we contro the Huid, required for a successful flushing. t

The featurel of the operating means, is the slot M, in the fin er K, whereby the relief valve O is allow to close, whilethe finger K, still holds the main valve P,`in the open position, see Fig. 3. The rule-joint4 L, in the finger K, may be used,to allow the said finger K, to swing in one direction, when the operating means, -is returned to its starting position, before closure of said mainv valve H 1 ,ormai 1 vnot necessary, for the'operating means be returned, toits startingposltion, before closure of said main valve P.

' The refilling of the. tank A, with the reuired amount of air and water, necessary or a successful fiushing, is a feature; and

' this refilling of said tank A, is accomplished as follows,-water is allowed to flow,

into said tank A, by way of the inlet opening I. As the water, under pressure, fiows past the check-valve z, raising said checkmive h, to position of oaed linea', Fig. 2, the water is conducted through the pipe H, and ydelivered to the elbow H;,at this point the water encircles a pipe RW; and as the water is forced, onward, under pressure, past the pipe R, a suction-or aspirator action is created, at the end of the pipe R", thereby opening the intake air valve m, to the position, m as indicated by the dotted line, Fig. 2, and allowing the required amount of air, to enter, by way of the inlet R, and the pipe R', and mix with the-water, in the pipe Hm', to'be delivered to the inside of said tank A. This aspirator action of air, into said tank A, actuated by, and simultaneously with, the intake of 'water, assures the required amount of air, necessary for a. successful flushing, from said tank A by the time, the said tank A, has

v receive( its required amount of water. As

soo-n as the air and water pressure, within the tank A, equals the water pressure in the service pi-pe, the said air-valve m, and the said check-valve L, will be closed, automatically, as shown in Fig. 2, and prevent the contents of said tank A, from escaping by way of the respective, intake pipes, R',

and H.

With the special features thus described, l

my device operates as follows:-In Fig.

2, all valves are in the closed position; as

soon as water is allowed to pass the inlet opening I, the check-valve la., by the action of the water, is opened tothe position L, as indicated by the dotted Irline, Fig. 2.

Water passing the check-valve h, flows` of pipe RWA, a suction or aspiration is created, at the end of pipe R, and thereby the air-valve m, is elevated tothe open position, m, as indicated by dotted line, Fig. 2. With the check-valve h, and the air-valve m, in the open position, as indicated by the dotted lines, via/,and h', Fig. 2, air is .drawn through the pipe R", and mixed with the intake of water, within the pipe II, and delivered to t-he inside of said tank A. Water will continue to flow, into said tank A, until the air and water pressure therein, equals the pressure of the wat-er in the service pipe, at which point,

the said tank A, is filledwith air and water,

a corresponding pressure is forced between the inner wall 4of said valve-casing, part B, and the outer wall of thesaid main valve P, into the confined chamber X,

thereby forcing the said relief valve O, and the said main valve P, downward, upon their respective valve-seats, .and forming a positive closure of said valves, O, and P. With the said tank A, filled to its capacity, a downward motion of the handle D, will rotate the spindle E', upon its axis, and elevate the finger K, which delivers a corresponding pressure upo-n thel end, of the apertured valve-stem O, thereby opening the relief valve O, Fig. 3, and allowing the contents of chamber X, to be discharged through the apertured valve-stem O, into the housing, within the depending valvestern P, and onward through the opening o, to be delivered to the discharge pipe G. With the pressure of air and water, in the confined chamber X, released by way of the passage-way o, o', within the valvestem O', a continued downward pressure upon the handle D, will deliver a correspending pressure, by means of finger' K, upon the end of the depending valve-stem, P, and thereby open the said 'main valve P, see Fig. 3, and allow the contents of said tank A, to be discharged, under direct pressure, through the openings, g, g', in the Vvalve-casing, part B, to the openings, l,

2', 3', 4', in the regulating plate c, c', and their corresponding openings, 1,-2, 3, 4,', in

the valve-casing, part B', and onward to i the discharge pipe G. .As the main valve P, is fully opened, see Fig. 3, the depending valve-stem vP, changes its position, on the finger K, and presents the distal end, of the apertured valve-stem O, to the slot M, in said finger' K, thereby allowing, the distal end, of said apertured valve-stem O', to fall into the said slot M, with closure of said relief valve. O. while the finger K, is still in contact, with the depending valve-stern P, and holding the said main valve P, in its full open position. As soon as the handle D, is released, the o erating means, D, E, K, will return to its starting4 position, see dotted line, K', Fig. 5, and leave the relief valve, O, closed, and the main valve, P,

open. The main valve P, being a gravity actuated valve, will return to its closed position, and leave the device ready, to repeat its operation, as shown in Fig. 2.
